This is the magic switch:
http://www2.cip1.com/ProductDetails.asp?Pr...C-111-953-519-GIt has electric contacts for the electric pump so your car stays stock.
Use any water pump, just mounted it bellow the water tank and drill a hole in the tank cap (I drilled the valve).
This is the switch you need. It has wiring for the electric pump. It's that extra black wire that you see in the picture. You don't need to use the water hoses under the dash anymore. Except the extra wire, its exactly the same as the original.
You do have to route a wire from the pump to the switch.
Personally, I hate adding buttons to the dash so this solution was nice and neat for me.
If you want to, you can also modify your old switch to operate the pump. I have a post about that somewhere. I finnaly opted for the new switch since I wanted an intermittent relay as well and my old switch didn't have the contacts for that.
BTW, the switch still has the pipes for the under-dash hoses. You don't use them, you can take that part off.
